POSSIBLE CAUSE
Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or clips.
Severely discharged battery, but
otherwise it is a good battery.
Reverse connections at battery.
Transformer laminations vibrate (buzz).
Shorted Diode Assembly or Output
Rectifier Assembly (hum).
Drawing more than the Engine Start rate.
Failure to wait 3 minutes between
cranks.
Clamps are not making a good
connection.
AC cord and/or extension cord is
loose.
No power at receptacle.
The charger may be overheated.
Battery may be severely discharged.
The settings may be wrong. Check the
charger settings.
Have the battery checked.
Circuit breaker cycles when current
draw is too high. Check for shorted
cables or clips and replace if
necessary.
The battery may not want to accept a
charge due to a run-down state. Allow
charging to continue until battery has a
chance to recover sufficiently to take a
charge. If more than 20 minutes, stop
charging and have the battery checked.
Shut the charger off and correct the
lead connections.
No problem, this is a normal condition.
Have charger checked by a qualified
technician.
Crank time varies with the amount of
current drawn. If cranking draws more
than the Engine Start rate, crank time
may be less than 5 seconds.
Wait 3 minutes of rest time before the
next crank.
Check for poor connection at battery
and frame.
Check power cord and extension cord
for loose fitting plug.
Check for open fuse or circuit breaker
supplying AC outlet.
The thermal protector may have
tripped and needs a little longer to
reset. Make sure the charger vents are
not blocked. Wait and try again.
On a severely discharged battery,
use the 25A Boost setting for 10 to 15
minutes, to help assist in cranking.
